KDE battery monitor


Dear lazyweb,

using a ThinkPad X1 Carbon with Debian unstable and KDE 4.14.2, I have not had battery warnings for a few weeks, now.

The battery status can be read out via acpi -V as well as via the KDE widget. Hibernation via systemctl hibernate works as well.

What does not work is the warning when my battery is low, or automagic hibernation when shutting the lid or when the battery level is critical.

From what I gather, something in the communication between upower and KDE broke down, but I can’t find what it is. I have also been told that Cinnamon is affected as well, so this seems to be a more general problem

Sadly, me and anyone else who’s affected has been unable to fix this.

So, dear lazyweb, please help.

In loosely related news, this old status is still valid. UMTS is stable-ish now but even though I saved the SIM’s PIN, KDE always displays a “SIM PIN unlock request” prompt after booting or hibernating. Once I enter that PIN, systemd tells me that a system policy prevents the change and wants my user password. If anyone knows how to get rid of that, I would also appreciate any pointers.
